Use a Volt Meter for RC Batteries

RC model cars require rechargeable battery package packs to operate. These battery power slowly, after many recharges, begin to lose their ability to be billed to highest possible potential.

The highest possible current potential of an assortment power, or affordable current, is clearly marked on each RC car's battery package power. Use a multi meter set to measure v to determine how close to the affordable current your remote control battery package actually is after a recharge. This information can help you decide if battery package needs alternative. A battery package billed to its affordable current will allow an RC car to race and perform exciting stunts longer.

Remove the RC battery package power from your toy.

Plug the RC battery package power into its battery charger and fully charge it for the time specified by the maker. Completely charging battery package power will ensure it has the highest possible current possible in its current condition.

Disconnect battery package from the battery charger.

Turn on the voltmeter and then select the dc current setting. Typically this is designated by a capital "V" with straight lines above it or the letters "DC." Frequently the dial will contain a number of DC current settings labeled by specific ranges. Make sure to choose the range that includes the current listed on battery package.

Place the red positive lead of the multi meter in the left opening on the RC car battery package connect.

Position the black adverse lead of the multi meter in the right opening of the RC car battery package connect. Read the current from the screen. A bad value just means that you have switched the leads of the connection. Disregard the adverse sign and compare the current to that written on battery package.

Replace battery package if the current reading given by the voltmeter is 10% more or less than what the maker has specified. Multiply the current written on battery package by 0.10, then subtract the result from the original current to get the smallest appropriate current. For example, if the affordable current is 12 v, the smallest appropriate current before alternative is 12 minus 12 times 0.10, or 10.8 v.
